United States Patent C 3,001,723 VALVES AND NOZZLES Wallace A. Bounds,3726 135th Ave. SE., Bellevue, Wash. Filed Oct. 30, 1958, Ser. No.770,793 9 Claims. (Cl. 239-448) The invention relates to improvements ina combination of valves or nozzl in which the advantages of amomentarily adjustable nozzle valve are combined with the advantages ofa momentarily adjustable lilood valve.

The principal object of the invention is to provide the advantages anduse of each valve at virtually the same time and in the same device sothat a liquid will emerge from the device when it is so set in thedesired range of from a trickle to full ood with scarcely more than theforce of gravity; and when alternately set, in the conventional forcefulspray patterns of an adjustable nozzle; or, the combination in alternateform, will mix dissimilar substances upon elnence. Such a device willprovide the gardener with the Afull range of water efEluent choices; notjust the nozzle pattern half. In addition to conventional nozzlepatterns the flood valve provides la means of placing measured amountsof water more precisely and upon delicate plants which might otherwisebe damaged or destroyed by a pressurized spray.

One form of the invention is illustrated in the accompanying drawingwherein an essential portion of a conventional nozzle Valve is itselfmounted inside a housing, the whole forming an integral combination ofconcentric valves having a common antechamber. Each depends foractuation on the same common actuating means. When the nozzle valvebarrel is turned or rotated ll revolution the means of locking the floodvalve closed and unlocking it prevents or permits the ilood valvebetween it and the housing from being opened or to be opened.

The accompanying drawings illustrate the preferred details ofconstruction wherein:

FIGURE l is a side view in partial section showing the nozzle valve inthe closed position and the ood valve in the locked closed position.

FIGURE 2 is a side view in partial section showing the nozzle valveclosed and the ood valve open.

FIGURE 3 is an enlarged end view from the plane 3-3, FIGURE 1.

FIGURE 4 is an enlarged end view from the plane 4-4, vFIGURE 2.

FIGURE 5 is an enlarged sectional view showing means of sealing ingreater detail.

The flood valve and nozzle valve combination may be constructedsubstantially as shown in FIGURE l in which a body frame housing 1 isformed and machined as necessary for attachment in a conventional mannerat end 2 to the end of a garden hose. It includes an outer barrelportion 3 to internally and coaxially receivev an inner nozzle barrel 4and an independent resilient means in the form of a compression spring5. At the inner end of barrel 3 is a resilient washer 6, a non-resilientwasher 7, an O shaped or torus ring resilient seal 8 and a packing gland9 -having a slot 10 for driving purposes. One end of barrel 4 projectsbeyond the end of barrel 3 as shown in FIGURE 5. On nozzle barrel 4 isan integral annular shoulder 11 which serves on one side as a stop forthe spring 5 and as a valve seat on its opposite surface in cooperativeengagement with the annular ring seat 12. The ring 12 is an integralpart of housing barrel 3. A resilient sealing washer 13 is positionedbetween the parts, 1-1 and 12. The nozzle valve formed by nozzle barrel4, nozzle needle piece 20, seats 22 and 24, washer 23 and spring 21,depends upon Mice a locking means for retaining the inner barrel 4 infixed relationship to the outer barrel 3 which means is in the form offour circumferentially spaced lugs 14 integrally positioned on theinterior of barrel housing 3 `as shown and against which the four lugs15 bear or are engaged when barrel `4 is locked in position as shown inFIGURE l and FIGURE 3. Lugs 14 also serve as centering guide surfacesfor the axial or reciprocal movement of nozzle barrel 4. The innerbarrel 4 is reciprocally contained within the outer barrel 3 in spacedrelation thereby. When barrel 4 is locked in this position with respectto barrel 3 =as shown in FIGURES l and 3 -manual depression of handle 16in the form of a first class lever with fulcrum pin 17 through thehandle 16 and trunnion lug 18 on body frame housing 1 las shown bearsagainst knurled adjusting nut 19. The adjusting nut 19 is screwed ontoone end of the axially movable shaft of nozzle needle piece 20. Theforce of an independent resilient means in the form of a compressionspring 21 is overcome causing nozzle needle piece 20 to move theintegrally formed nozzle seat shoulder 22 away from washer 23 and seat24, an integral part of nozzle barrel 4, thereby opening the nozzlevalve in the conventional manner. The seats 11 and 12 and washer 13 forma ood valve which is normally held in closed position by the spring 5.

The axially movable shaft of nozzle needle piece 20 near the knurledcollar 32 end of barrel-4 is sealed in nozzle barrel 4 by means ofresilient seal 25, non-resilient washer 26, an O shaped or torus ringresilient seal 27, and packing gland 28, having slot 29 for drivingpurposes. Nozzle barrel 4 is internally threaded with threads 30 toreceive packing gland 28. Mounted between nozzle needle piece seatshoulder 22 and resilient washer 25, yand around nozzle needle piece 20,is ya lirst independent resilient means in the form of a compressionspring 21. Compression spring 21 is suiciently strong to force nozzleseat 22 against washer 23 and seat 24 forming an eective seal and nozzlevalve closure. The second resilient means, compression spring 5,positioned between annular shoulder 11 on nozzle barrel 4 and resilientwasher 6, and 'around nozzle barrel 4, is suiciently strong to forcevalve seat 11 against washer .13 and seat 12 forming an effective valveseal. Compression spring 21 is sufficiently stronger than compressionspring 5 and liquid line pressure so that when lugs 15 are disengaged byrotation of nozzle barrel 4 from lugs 14 as shown in FIGURES 2 and 4yand :handle 16 actuates nut 19, nozzle barrel 4 will move axially withrespect to housing barrel 3 opening the ood valve `formed by seats 111and 12, washer 13, nozzle barrel 4, housing barrel 3 and spring 5.Because spring 21 is suciently stronger than spring 5 and line pressure,nozzle piece 20 will not move with respect to nozzle barrel 4 but bothwill move with respect to barrel 3 so that the nozzle valve, Iformed byvalve seats 22 and 24, washer 23, nozzle needle piece 20, nozzle barrel4 and spring 21, will remain closed. Rotation to disengage and engagelugs 15 on nozzle barrel 4 with lugs 14 on barrel 3 is eiected by `amanual torque applied on knurled collar 32, an integral part of nozzlebarrel 4. An inlet hole 33 through the side of nozzle barrel 4 as shownpermits liquid to enter nozzle barrel 4.

The opening actuation of each valve depends upon a common means whichincludes the handle 16, fulcrurn pin .17, trunnion lug 18 on bodyhousing frame 1, the knurled adjusting nut 1 9, the axially movableshaft of nozzle needle piece 20 and the shoulder 22. The closingyactuation of each depends upon independent resilient means in the formof compression springs 5 and 21, one of greater force than the other.Spring 21 must be stronger than spring 5 so that the flood valve may beopened by force transmitted through spring 21. In this respect when lugs14 and 15 are disengaged as shown in FiGURES 2 and 4 and since spring 5is weaker than spring 21, spring21 acts as a solid non-resilient meansmoving nozzle barrel 4 and compressing spring 5 and thereby opening theood valve.
